Question

a+b=c
c=a*b-(b-a)
explain the equation

Answer 1

Answer:

75

Step-by-step explanation:

We have,

If a+b+c+ab+bc+ca+abc=2005

We know that,

(a+1)(b+1)(c+1)=a+b+c+ab+bc+ca+abc+1

⇒(a+1)(b+1)(c+1)=2005+1

⇒(a+1)(b+1)(c+1)=2006

⇒(a+1)(b+1)(c+1)=2×17×59

⇒(a+1)(b+1)(c+1)=(1+1)(16+1)(58+1)

On comparing that,

a=1,b=16,c=58

Then,

a+b+c=1+16+58

a+b+c=75
